Relevant operations of this software.



1.How to Set the Probe Attenuation Coefficient

The probe has several attenuation coefficients, which will influence the vertical scale factor of the oscilloscope.
To change or check the probe attenuation coefficient in the menu of oscilloscope:

(1) Click

to show Function menu, choose "Channel".

(2) Set "Probe Rate" to the proper value corresponding to the probe.

This setting will be valid all the time before it is changed again.

Caution:

The default attenuation coefficient of the probe in the software is
preset to 10X.
Make sure that the set value of the attenuation switch in the probe is
the same as the menu selection of the probe attenuation coefficient
in the software.

The set values of the probe switch are 1X and 10X.

Figure: Attenuation Switch

Caution:

When the attenuation switch is set to 1X, the probe will limit the
bandwidth of the oscilloscope in 5MHz. To use the full bandwidth of
the oscilloscope, the switch must be set to 10X.
